David Burton
I build systems that learn from data.
Founder of Klytotech LLC — building production AI systems for healthcare, biotech, and finance.
Klytotech LLC
Quantitative finance, clinical research, biotech. Different domains, one discipline.
I run a one-person research and engineering studio: production ML and data infrastructure for clients in healthcare, biotech, and finance, built end to end. The rigor behind a trading system's risk layer is the rigor behind a clinical study's propensity matching, and moving between them is what keeps the work interesting.
- End to end From data ingestion to production monitoring. I own the whole pipeline, not a slice of it.
- Production-grade Real capital and clinical data depend on these systems. They ship, and they stay up.
- Open by default The tools I build for my own work become public libraries on GitHub, documented and tested.
- Self-directed The best questions are usually the ones nobody handed me.
